National Geographic Automatic 90/1250 Telescope

1. Automated GoTo Mount: The National Geographic Automatic 90/1250 Telescope features an integrated altazimuth GoTo mount that automatically locates and tracks over 270,000 celestial objects. This ease of use makes it perfect for novice astronomers eager to explore the night sky without manual star-hopping.

2. Maksutov-Cassegrain Optics: This telescope employs a Maksutov-Cassegrain optical design, a catadioptric type that uses both mirrors and lenses to achieve a long focal length in a compact tube. This design is highly celebrated for delivering sharp, high-contrast images with minimal chromatic aberration, making it excellent for detailed views of the Moon, planets, and double stars.

3. High Magnification Potential: With a substantial 1250mm focal length paired with its 90mm aperture, this telescope offers significant magnification capabilities. It allows observers to zoom in on intricate lunar craters, the planetary rings of Saturn, and Jupiter's prominent moons, bringing distant celestial bodies into impressive view.

4. Robust Construction: Built for stability and durability, the telescope rests on a sturdy steel tube tripod. Its optical tube is typically constructed from high-quality aluminum, ensuring longevity and consistent performance across various observing sessions. This rigid design minimizes vibrations, providing a more enjoyable viewing experience.
